TouchGFX migration from STM32F7 to STM32H7

[S.P.]

We are using STM32F7 with TouchGFX and considering in migrating it to STM32H7 series. May we know how much effort is needed to migrate those TouchGFX things from STM32F7 to STM32H7? Is it easy?

Thanks.

Painting things in to a frame buffer, and associated software will of course be much the same.

The H7 is HARD, it's architecture is different and challenging. Newer versions will compound this.

Review the Reference Manual and Data Sheet to better frame the discussion.

Currently available steppings don't support DSI displays. The different bus domains mean you need to pay attention to the memory you use for the frame buffer.

Hi S.P!

I can't speak for your hardware configuration, but in terms of TouchGFX Applications the gui part can be moved onto any micro. Possible concerns when porting in terms of application: The amount of memory used for buffers (Canvas widgets, Dynamic bitmaps, ...).

I'd be happy to get more specific if you can share more information about your current solution.

Best regards,

Martin
